Children often have the problem of circumcision or phimosis, with phimosis or phimosis if there are no complications can not be circumcision. Pediatric circumcision can grow with age, the head of the penis and the inner plate of the foreskin epithelialization and disappear on their own, some children only need to repeatedly retract the foreskin upward, expand the opening of the foreskin, revealing the head of the penis to peel off the foreskin adhesions, and do not have to be surgical treatment. It should be especially reminded that some children belong to the hidden penis, not purely circumcised or phimosis, should not be circumcision; some obese children with poor penile exposure, should be careful to choose surgical treatment. Children with phimosis and priapism should not be operated for the time being, and should wait until the inflammation subsides before the operation can be carried out.
